1 Claim. (Cl. 211105.5)

The present invention relates to a tightening device for spannedcurtains on windows, glass doors and the like parts in a building.

The hitherto conventional metal and glass rods used for the fixing ofspanned curtains are fastened by means of screws which cannot always befastened sufl'iciently to resist the stress when the curtains arespanned out tightly. Furthermore the metal rods oxidise thus dirtyingthe curtains, and when exposed to a heavy load they will bend, whereasglass rods will easily break. Moreover, it has often been difficult toget rods of the correct length corresponding to the width of the spannedcurtains.

The object of the present invention is to provide a cheap tighteningdevice by using less material and without using screws for the metal andthe timber, a longer durability by using corrosion resisting materials,a more secure fastening of the spanned curtains and a simpler and easiermounting.

This is obtained, according to the invention, by using tighteningdevices comprising small dowel nails glued into the window or the doorand provided with incisions in which a cord of an artificial substancepassed through the running of the curtain may be secured firmly.

An example of the manner of construction of the object of the inventionis illustrated in the drawing, in which Fig. 1 shows a section through awindow frame with the dowel nail glued in, and

Fig. 2 part of a spanned curtain arranged on the upper frame portion.

In order to secure the tightening device there is in each corner of thewooden window frame glued in a dowel nail 1 having a horizontallyextending slot 2.

Through the running of the spanned curtain there is now drawn a cord ofa strong and somewhat yielding artificial substance, preferably a perloncord 4, one end of which is provided with a knot 5 which is greater thanthe cross section of the slot of the dowel nail, and is thereaftersuspended in the slot. When the perlon cord has been cut off in thelength corresponding to the tightening it is desired to give the spannedcurtain, the free end is passed through a knob, e.g. a cone or a ball,and on the outer side there is now made a knot. The knob is used wheninserting the perlon cord in the slot of the dowel nail or the cord maybe shortened in such manner that the cone 3 rests firmly against thedowel nail when the cord has been tightened.

What is claimed is:

Drapery hanger arrangement, comprising, in combination, a frame havingone main face and two bores of predetermined diameter and depthsubstantially perpendicular to said face and located at the samehorizontal level and spaced from each other; a dowel member inserted ineach of said bores and attached to said frame so as to have an endportion projecting from said face, said projecting portion beingprovided with a slot of predetermined width and extending in a directionsubstantially parallel with said face of said frame; a cord made ofresilient synthetic material and formed with knots at a distance fromeach other shorter than the spacing of said dowel members, two portionsof said cord adjacent said knots, respectively, being inserted in theslot of one of said dowel members with the respective knot located onthe side of the respective dowel facing away from the other dowelmember, and a knob member having said cord extending therethrough andsaid knob being located between one of said knots and the adjacent dowelmember when the cord is inserted in said slots.
